Implement Nginx Ingress features based on Gateway API

[CH3CHO]

Why do you need it?

Nginx Ingress provides a lot of routing features via annotations. We need to migrate them to the new configuration model of Gateway API.

How could it be?

• Summarize all the routing features provided via annotations. Find out which are already supported by Gateway API, and which are not.
• Submit proposals for the latter ones.
• Implement these features with Gateway API

We can implement features already supported by the Gateway API by contributing to the ingress2gateway community , and integrate this project.

我最近调研了higress注解功能在gateway api中的支持情况，详见https://docs.google.com/document/d/1rVmn_SOKZ8XbAZwVIORdaA-IghnivTnbculjZ_0_8NQ/edit#heading=h.dzoqm1w6kagf
